Questions

1 –– Characterize the news data sources provided. Which are primary sources and which are� derivative sources?� What are the relationships between the primary and derivative sources? Please limit your answer to 8 images and 300 words.

1.1 Characterize the news data sources provided. Which are primary sources and which are derivative sources?

First, we can overview the distribution of the characters of all news in Fig1.1.1.

Fig1.1.1 News Characters Distribution View

After exploring the topics and selecting the news of interest, the results panel will display news covering the same event and show which are primary and which are derivative. (Fig1.1.2)

Fig1.1.2 Result Board

Let's see an example:

Several news reported that Minister Nespola champions added taxes on oil, gas development in 1999 July.

We can find in the Fig1.1.3 that:

primary source: Kronos Star_488.txt

derivative source: International News_821.txt News Online Today_640.txt The Guide_327.txt The Truth_724.txt Worldwise_659.txt Homeland Illumination_468.txt All News Today_612.txt Daily Pegasus_482.txt News Online Today_267.txt The Orb_248.txt The Wrap_740.txt

Fig1.1.3 Exploring processing

The rest examples are shown in the Fig1.1.4:

Fig1.1.4 some examples about primary and derivative source

1.2 What are the relationships between the primary and derivative sources?

1.2.1 ”Copied News”: the primary and derivative sources report the same event and the derivative follows the statement of primary by using similar phrases or sentences, which was suspected of plagiarism. (Fig1.2.1)

Fig1.2.1 "Copied News" example

1.2.2 "Multi-perspectives": the primary and derivative sources report the same event from different perspectives. (Fig1.2.2)

The blue reported the event itself.

The brown related it to the POK movement.

Fig1.2.2 "Multi-perspectives" example

1.2.3 "Follow-up Events": primary reported the event (the driver in the custody).

The latter news may report the follow-up progress of the event (the driver released). (Fig1.2.3)

Fig1.2.3 "Follow-up Events" example

1.2.4 "Details come later": more specific details than primary. (Fig1.2.4)

Fig1.2.4 "Details come later" example

2 –– Characterize any biases you identify in these news sources, with respect to their representation of specific people, places, and events. Give examples. Please limit your answer to 6 images and 500 words.

2.1 Characterize any biases you identify in these news sources, with respect to their representation of specific people, places, and events. Give examples.

We design a Sankey diagram (Fig2.1) to illustarte the biases in those news sources that reported the same event. The sankey diagram demonstrates the difference about the entities those news sources concerned in the same event, through which we can find their biases, with respect to their representation of specific people, places, and events.

Fig2.1 Sankey Diagram

2.1.1 News Online Today made brief statements of the events and was lack of antecedents, background and details which is probably because it is an online media. We can see that the news was very brief in Fig 2.1.1.

Fig2.1.1 one news article of News Online Today

2.1.2 When it comes to adding tax on oil and gas development, although all news sources pay attention to the event itself, only The Warp, All News Today and The Orp related it to POK. We can see that the entity POK only showed up in these three sources in Fig 2.1.2.

Fig2.1.2 sankey diagram of articles about adding tax on oil and gas development

2.1.3 When it comes to kidnapping and ransom demand, only four sources mentioned the Abila Police Department. (Fig2.1.3)

3 –– Given the data sources provided, use visual analytics to identify potential official and unofficial relationships among GASTech, POK, the APA, and Government. Include both personal relationships and shared goals and objectives. Provide evidence for these relationships. Please limit your answer to 6 images and 400 words.

3.1 Identify potential official and unofficial among GASTech, , the APA, and Government. Include both personal relationships and shared goals and objectives. Provide evidence for these relationships.

The challenge background is kidnapping, choose a topic that contains the most number of articles, top10keywords contains kidnapping, through force-directed graph 's co-existence network, we can see that kidnap is relevant to sanjorge (GAStech's President and CEO), kaplou (president of Krono). Left news shows that kaplou and sanjorge attend an event(1) at the same time, krono government should have a better relationship with gastech. At the same time in kaplou's co-existing network Elian Karel (pok former chief) shows. news shows that POK called for kapelou to step down.(2)moreover pok's protest ignored and firmly suppressed by kronos shows that , the kaplou government is in favor of gastech. The reason for the kaplou government's favor is clearly shown in the kaplou co-existence network in other topics. gastech has a cooperative relationship with the krono government, and gastech contributes a lot of tax revenue to the krono government for infrastructure construction.(3)

Fig 3.1 GAStech & Kronos have a close relationship

It is clear from some news reports that kaplou took bribes from sanjorge to allow GAStech to continue operating in Kronos. (Fig3.2)

Fig 3.2 GAStech president bribes

And in Sanjorge's co-existence network appeared a person Edward Vann and the organization APA. the news shows that APA caused krono chaos Fig3.3(1), Edward Vann is suspected of participating in the kidnapping incident. Fig3.3(2)Therefore, after searching Edward Vann and kidnap, we found that Edward Vann was suspected of having shared a family name with Julian Vann, and the fire alarm that occurred at the crime scene was a false alarm to cover the escape of the criminal. Edward identified the kidnapping as possibly related to the IPO, and the fire alarm indicated that there might be a pokey mole within the company.Fig3.3(3) POK's leadership in the kidnapping was also finally confirmedFig3.3(4)

Fig 3.3 POK's leadership in the kidnapping confirmed

POk and APA both obtained money through drug traffickingFig3.4(1), APA created a publication called 'Arise' and sold drugs that used to be called 'flower' and 'spice', raw materials from cotton. APA is the source of Kronos drug.Fig3.3(2)

Fig 3.4 APA is the source of Kronos drug.

Some key figures were found in the previous exploration, sanjorge, Edward vann, Julian vann, etc., where Edward vann was accused of being a pok member because he shared the family name vann with pok member Julian vann. Isia.Vann also has the family name of vann, he used to work in the army of kronoFig3.5(1), and we also have his email information. We found something unusual in the subject of Isia.Vann's emails, he communicated with others about "flower", and there was a virus in his computer, and the subject of the correspondence - "FW: ARISE - Inspiration for Defenders of Kronos“ shows that he is a member of POK and is also involved in drugs.Fig3.5(2) We extracted the correspondents of the two email subjects. Fig3.3(3) We found that the emails from two subjects overlap, so we can basically decide that Hennie Osvaldo, Inga Ferro, Isia Vann, Loreto Bodrogi, Minke Mies, Rachel Pantanal, Ruscella Mies Haber are the traitors.Fig3.4(4)
